日前有消息稱，Windows Vista SP1將會把DirectX升級到10.1版本，使得剛剛購買了DX10顯卡的玩家很快就被“拋棄”，引發一片爭議，不過微軟官員近日又表示，DX10.1將完全支持現有的DX10顯卡，只是後者可能會無法實現DX10.1的所有特性而已。
微軟Direct3D開發團隊首席項目主管Sam Glassenberg在接受Next-Gen.biz電話採訪時稱：“DX10.1完全支持DX10硬件。我們沒有去掉任何硬件支持。(DX10.1)只是在DX10的基礎上略微擴展了硬件功能而已，嚴格地說就是一個超集。在DX9的時候我們也這麼做過。”
Glassenberg做出保證：“所有的硬件都會繼續得到支持，所有的遊戲都會照常運行，所有的特性都還在那裡。我們只是簡單地拓寬了一下特性集合和API接口的使用期。”
Glassenberg承認DX10.1裡“會有一些新特性，而且會在新硬件上得到體現，但這與DX9時代的模型類似，(只是)到了DX10.1，我們會(對開發人員說)，如果你們想支持新特性，就必須全部支持”，包括DX10裡的原有特性。換句話說，DX10.1基本上只是把DX10裡的某些特性由可選支持變成了強制要求。
盡管目前的DX10顯卡可能無法支持DX10.1的全部特性，比如3D渲染質量技術改進，但Glassenberg指出：“(DX10.1)只是一個小型升級，所以我們不希望有開發人員打出這樣的口號：‘嘿！這款遊戲是DX10.1專用的。’接下來幾年面世的遊戲都會從現有的DX10硬件上獲得越來越好的質量。”
至于支持DX10.1的顯卡何時上市，Glassenberg表示微軟的工作只是提出新規格、支持新硬件，具體產品什麼時候發布並不是他們說了算，得看顯卡廠商的。
此外，Glassenberg還再次肯定DX10是專為Vista打造的，會充分利用新系統的諸多新特性，不會“下價”到Windows XP。

DirectX 10 Hardware Is Now Obsolete

"SIGGRAPH 2007 was the stage where Microsoft dropped the bomb, informing
gamers that the currently available DirectX 10 hardware will not support the
upcoming DirectX 10.1 in Vista SP1. In essence, all current DX10 hardware is
now obsolete. But don't get too upset just yet: 'Gamers shouldn't fret too
much - 10.1 adds virtually nothing that they will care about and, more to the
point, adds almost nothing that developers are likely to care about. The spec
revision basically makes a number of things that are optional in DX10
compulsory under the new standard - such as 32-bit floating point filtering,
as opposed to the 16-bit current. 4xAA is a compulsory standard to support in
10.1, whereas graphics vendors can pick and choose their anti-aliasing
support currently. We suspect that the spec is likely to be ill-received. Not
only does it require brand new hardware, immediately creating a minuscule
sub-set of DX10 owners, but it also requires Vista SP1, and also requires
developer implementation.'"
